Full-back Jesse Mogg scored two tries for the Brumbies, as they defeated Australian conference rivals Queensland 24-6 in their Super Rugby opener at Canberra Stadium.

In a contest that rarely reached any great heights, the Brumbies dominated the Reds at the breakdown to claim a well-deserved win.

The Reds, who finished 2012 as the Australian conference winners, were let down by a lack of discipline and were punished by referee Andrew Lees.

The winning margin could have been even greater but the Brumbies goal kickers had an off night, missing four penalty attempts and failing to convert Mogg's first try.

"They beat us twice last year and you try not to carry things over between seasons, but that really hurt us and we weren't happy," Brumbies captain Ben Mowen said.

"We left a lot of opportunities out there but I'm really happy with that [victory]."

Mowen says the Brumbies forward pack, which has been bolstered by the recruitment of Wallabies flanker David Pocock, laid the foundation for the win.

"The breakdown is obviously a huge strength for the Reds and I think we matched them there tonight," he said.

The Reds opened the scoring with a 51-metre penalty goal to Mike Harris in the third minute, but the Brumbies hit back soon after with a try in the corner to Mogg.

In a tight and somewhat dour first half, Harris kicked his second penalty to put the Reds back in front.

However, on the stroke of half-time, Brumbies half-back Nic White booted a penalty goal to send the hosts into the break leading 8-6.

The second half was almost a carbon copy of the first, but the Brumbies gradually took control and crept ahead on the scoreboard with three more penalties.

The Reds only started to look dangerous in the last 15 minutes but they never really threatened the Brumbies goal line and Mogg rubbed salt into the visitors' wounds when he intercepted a Quade Cooper pass to score under the posts.

"It was really disappointing how we played tonight," Reds captain James Slipper said.

"The ill-discipline really hurt us and we let the Brumbies get good field position, and we just couldn't hang on.

"I don't think we gained any momentum through the forwards and we couldn't deliver any good ball to the backs."
